Claim This BusinessJust One Call, Inc. has served Glendale and surrounding communities since 2005, building a licensed HVAC operation that spans Glendale, Burbank, Monrovia, and Los Angeles County. The company holds a 4.5-star average from 160 reviews, reflecting nearly two decades of residential heating, cooling, and indoor-air-quality work. Extended hours from 7 AM to 9 PM cover every day of the week, including weekends. Homeowners in Glendale and nearby neighborhoods can request same-day service or schedule in advance for installations and planned maintenance.
What distinguishes this contractor is a lineup of manufacturer partnerships and specialized trades rarely found under one roof. As a Mitsubishi dealer, the company installs variable-speed heat pumps with performance warranties backed by the factory. Smart thermostat options include recognized brands for wifi-enabled comfort control. Beyond climate systems, Just One Call lists plumbing and electrical among its capabilities, along with advanced indoor-air-quality equipment such as REME HALO whole-home purification, UV coil sterilization, and whole-house humidification and dehumidification. Financing plans and energy-efficiency consultations round out an offering aimed at full-system performance rather than single repairs.
Reviewers repeatedly name two technicians who shaped their experience. Arthur coordinated a complete heating-and-cooling replacement, including ductwork that failed inspection and required a change order, yet kept the customer informed at every stage and sent a cleaning crew after installation dust settled. When Teo Aghazarian faced a failed air conditioner during a particularly hot week, David arrived the same day and restored comfort quickly, earning high marks for speed and professionalism. Bri Rodriguez echoed the same theme: rapid response, clear explanations, and knowledgeable execution that left her confident enough to recommend the company for any HVAC or plumbing need.
Every reviewer awarded 5 stars, with no negative feedback present in the available sample. Four of six reviewers explicitly mention same-day or next-day arrival during urgent breakdowns. Arthur appears in two reviews as the primary point of contact, and David earns praise for rapid response during extreme heat.
